Blake Shelton and Gwen Stefani might have more than one reason to celebrate the coming holiday season as gossip reports claim that the singers are already expecting their first baby together. The music power couple, who met on the sets of The Voice, have not shied from expressing their love for each other in public and for quite some time now, rumours of their wedding have been doing the rounds.

A latest report by Life & Style magazine (via Hollywood Life)has claimed that Stefani, who recently turned 47, has been planning a Christmas wedding at her boyfriend's home in Oklahoma.

In addition to the grand nuptials, the magazine reported that their friends "believe she [Stefani] could already be pregnant".

Gossip Cop suggests that the Hollaback Girl hit-maker is neither pregnant with her fourth baby nor is she getting married to her country singer beau during Christmas holidays.

The debunk report follows a cover story that said: "Blake Shelton is set to become a first-time dad [and third-time husband!] with Gwen Stefani by his side." It further claimed that the mother-of-three "has been planning a blowout Christmas wedding and trying to get pregnant."

"She's been eating a lot of carbs, which she never eats except when she's pregnant," the report mentioned adding that this time the Used To Love You songstress "wants a baby girl after years of feeling outnumbered at home".

Meanwhile, during an appearance on The Ellen DeGeneres Show, the Rich Girl singer appeared all smiles when the chat show host asked her about tying the knot with Shelton.
